LUBRICATING SYSTEM.

Specification of Letters Patent.

Application filed November 25, 1907. Serial No. 403,621.

To all whom it may concern:

Be it known that I, WILLIAM J. SciiLAons, a citizen of the UnitedStates, residing at Chicago, in thecounty of Cool; and State ofIllinois, have invented certain new and useful Improvements inLubricating Systems, of which the following is a specification,reference being had therein to the accompanying drawings.

My invention relates to a lubricating sys tem for locomotives and thelike, and comprises as its essential parts a lubricating mechanismhaving a rotatingshaft, and a mechanism intermediate the lubricatingmechanism and a moving part of the device to be lubricated, such as therockerarm of an engine, and adapted to transmit rotary movement to theshaft.

In the accompanying drawings, which illustrate an embodiment of mypresent invention-Figure 1 is aside elevation of a locomotive equippedwith my present lubricating system, the cab being broken away to showthe oil pump located therein; Fig. 2 is a sectional view of one form oflubricating mechanism which may be employed;

Fig. 3 is a front elevation of the transformer with the face plateremoved; Fig. 4: is a vertical sectional view of the transformer on theline 4-l of Fig. 5, and Fig. 5 is a horizontal view of the transformeron line 5-. of Fig. 3.

The locomotive shown is of the usual construction comprising among otherthings a boiler, cab, steam chest 7, and rocker-arm 8 of thesteam-distributing mechanism.

The lubricating mechanism comprises an oil-reservoir 9, preferablymounted in the cab adjacent the engine controlling mechanism so as to beunder the immediate observation and supervision of the engineer, and oneor more force-feed pumps 10 of any suitable construction mounted in thereservoir and adapted to be actuated by a drive shaft 11. Theselubricating pumps are shown in Fig. 2, and in general construction andmode of operation are the same as the double-acting pumps disclosed byLetters Patent of the United States No. 797,867, to I. A. Randel, datedAugust 22, v1905, to which reference is accordingly made for a detaildescription thereof, it being understood that any.nuniber of these, orother suitable, pumps may be mounted in the reservoir, with their headssuitably connected to actuating yokes 12 cooperating with cams oreccentrics13 on the drive shaft. The reservoir is provided withasuitable'supply ,opening, and the discharge pipes 14 lead reservoirinto the casing of a transformer- 16 suitably mounted by its base 17upon the engine. In the embodiment shown the transformer is outside ofand in front of the cab practically in horizontal alinement with the Oilreservoir, but it obviously may be set at different positions andelevations on the engine, and for this purpose the shaft 11 may haveflexible portions or sections 18 to accommodate itself to the differentlocations or elevations of the transformer. Obviously the shaft may beof the ordinary flexible type, but I' prefer to construct it with jointsor flexible sections as stated.

The casing of the transforn'ier is provided in its side wall with abearing.,19 for the shaft 11, which extends into the casing where it isprovided with a bevel-gear 20. the bearing having a suitablestufiing-box 21. The casing is in the form of a cup or reser- ,1 voir,and comprises a head 22 suitably secured in place by screws 23. and isprovided with a suitable .filler 24 in its top. The head or closure hasa central bearing'for a cross-shaft 25 passing therethrough and providedwith a suitable stuffing-box 2G. The shaft 25 is provided on its outerend with any suitable means as the rocker-arm 27 adapted to be moved byany moving part or element of the engine to communicate rocking orreciprocating motion to the shaft; in the present cn'ibodiment the arm27 is connected by a link 28 to an arm 29 which .with the rocker-arm 8forms a bell-crank lever; either or both arms 8 and 27 may be providedwitha series of holes shown in dotted lines in Fig. 5 so that theconnection may be adjusted to vary the throw or movement of thecross-shaft. The inner end of the shaft 25 is reduced and is seated in abearing 30 in the opposite wall of the casing, and the shaft is heldagainst longitudinal displace ment by a suitable pawl-lever 31 pinnedthereon and bearing against the inner face of the head. The shaft 25carries a sleeve 32 loosely mounted thereon adjacent the pawl-lever-andprovided with a bevel-gear 33 meshinggwitlis thegear- 20. The-shaft isheld from: longitudinal displacement bythecoiiperationzofftlidpartsijust described. The sleeve isiprovidediwith a: ratchet wheel 34 splinedthereto: between the pawl-lever 32landgean=33tliez diameter ofthe'; wheel being somewhat. less; than; thelength of the pawl lever. The; rocking or reciprocating movement offsha-tlz causes the pawl-lever to .similarliy move; and its motion istransmitted to the ratchet-wheel 34: bypawls' 35- loosely mountedonpivots 36 on the pawlF-lever and extending into the plane of theratchet wheel and engaging; the teeth thereof; The endsof the pawlleven' are somewhat extended, and. each. emensilom provided at one enda; stop-pin passing through a Bella 2a timely epenihg-imthe associatedpawl,

and the other end with a to Wl'I-lltlll:

one: of a. spring: 39 the springbeing; wound upon. the associated pi t361 :11: at'its outer end enga' the pawl to it; register with the teeth:of the wheel.

G na or more dogs 10-are provided to prevent backlash of the; ratchetwheel, and preferahly the dogs are mounted on pivots 41 on 3 the innerface of the head 22-. They may be of any suitable form, and theconstruction illustrated are counterparts of the pawls 35 being providedwith similar openings to engage associated. stop-pins 42 and held to 35their work by sprin 43.

The ratchet, paw lever, gear 33, pawls, dogs, and shaft 25 are allconnected to the removable head 22, so that all of these parts form aunitary or self-contained structure so adapted to be assembled anddisassembled wit respect to the casing or support at one and the sametime by one and the same operation,'the gears 20 and 33 being placed inmesh when the inner end of the shaft is seated inits bearing 30. v Theremovable section or head forms a closure for the casing whichpreferably contains grease or lubricating oil for the operating parts,the stuflingboxes for the shafts preventing leakage, and the jointbetween thehead and easing being oil-tight'for this purpose.

The pawls are arranged'a half tooth apart so that one pawl operates at atime, the dogs being similarly arranged and operative, and a movementequal to one half of the pitch of the teeth'is obtained from eachmovement of a pawl. By this construction larger and heavier teeth may beemployed on the ratchet, thus reducing the wear and doubling theresistance to'the strain.

The transformer prevents the necessity of extending a reciprocating rodfrom a point.

Where the power is taken to the lubricating mechanism. It also changes,the rccipro eating motion of the rocker-arm or other parts of thesteam/distributing mechanism to rotary motion of; the pump-actuatingshaft, and reduces the more or" less extended throw or motion oi the,operating simple rotation OflElIGSlItIzft, By employing a separatetransformer; as distinguished f'rom a structure: wherein this transformm=ti'on is accomplished? withinthev pumping mechanism itself, the latteris simplified and reduced to the lfeast possible number of parts,whereby the liability of the lubricating :mechanism becoming deranged orinoperative is reduced to a minimum, and any trouble in the transformingdevices may be readily remedied without in any manner disturbiug thelubricating mechanism; by l 1 son of the unitary construction ororga-niation; or: thetranszliormer parts their assembliazgeand disassemlhlage are easily accomp shed by the. operator; Also, the best resare obtained by having; the pumpu-rg nurcl mnism located in proximity tothe engiuicanntrolliing mechanism, as the engineer is. thusenabl'edwithout leaving his place to observe and regulate the rate of feed ofthe v pumps, each of which is independently ndjustable by a set-nut 44which allows a greater or less lost-motion or sliding of the cross-head45 on the pump-plunger 4.6 in a manner now Well understood in the art,and as it is desirable to economize in the size of the oil reservoir inorder to occupy as liille space as possible at the engineers station,the independent transformer permits the oil reservoir to be so locatedwhile occupyinga minimum of space, and also aflords more room for oil inthe reservoir. The transformation of the motion is effected at a rightangle, and this is important for the reason that as the pump-actuatingshaft extends longitudinally of the engine the right-angled transformerplaces its rocker-arm parallel with the engine and so in appropriateposition to receive its movement from themoving parts of the engine. 1

\Vhile the system is illustrated in connection with a locomotive, it isof course obvious that it may be used upon other forms of engineswithout departing from the invention, and while I have described byinvention with relation to a structure in which its variousfeatures maybe embodied I do not limit myself to any such specific forms, as changes.in details and constructions fall within the scope of my invention.
